On January 17, 1950, 11 men steal more than $2 million ($29 million today) from the Brink’s Armored Car depot in Boston, Massachusetts. It was the perfect crime—almost—as the culprits weren’t caught until January 1956, just days before the statute of limitations for the theft expired.

The robbery’s mastermind was Anthony “Fats” Pino, a career criminal who recruited a group of 10 other men to stake out the depot for 18 months to figure out when it held the most money. Pino’s men then managed to steal plans for the depot’s alarm system, returning them before anyone noticed they were gone.
